guac_common_surface_dup() may send invalid PNG

    Details

      Description

      guac_common_surface_dup() fails to check whether the dimensions of the surface are 0x0. Though this is a perfectly valid state for a surface, it is not possible to send a 0x0 image (nor does it really make sense to try); the PNG encoding functions fail, producing an invalid Guacamole instruction and breaking the protocol stream.
